To all whom it may concern:

Be it known that l, ARTHUR M. DENNING, a citizen of the United States, residing at Crete, in the county of Saline and State of Nebraska, have invented certain new and useful Improvements in Devices for Rehabbitting Connecting-Rods, of which the following is a specification.

This invention relates to a device for rebabitting connecting rods, and especially that type of rod used by a certain inake of automobile.

The invention consists of a combined su port, mold and core, and of certain speo' features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings in which Figure l is a side elevation showing the complete device in use.

Fig. 2 is a lace view, one section oil the mold and core bein removed,

Fig, 3 is a longitudinal section, a connectin rod being also shown in position and re abbitted,

Fig. 4 is a face view of the removable portion of the mold and core,

in the drawings 1 designates a standard I which may be supported in an upright position by any suitable means The upper portion of the standard is angled and ofiset as at 2 and the lower portion carries a wrist pin 3. Adjacent the pin 3 is a threaded opening l. Midway the ends the standard has lateral extensions 5 which are provided with lugs 6 at right angles to the face of the standard, and through said lugs worlr cofiperating thumb screws I.

A thumb screw 8 also works through the opening 4. v

A cylindrical block 9 is secured to the inner face of the ofiset portion 2 by means of a screw 10, but for purposes of description may be considered as the fixed member oi the mold. This block carries a core 11 and is provided with an annular groove ll encircling till the base of the core and adapted to receive a fiange of a connecting rod 19.

A similar cooperating block 12 is provided with a core portion 13 and grooves it and with a central opening 15 adapted to fit over a pin 16 pro ecting centrally from the core 11, the outer end portion of the pin being threaded and the core 12; being, locked thereon by a nut 16,

lhe core 13 has a recess 17 and the core 11. a in 18 which engages said recess, so that tiers is no relative movement between the two core portions when secured in place.

ln use the connecting rod 19 has the end to be rebabbitted fitted over the core 11 and the core portion 13 is then placed in position, the two core sections engaging, and the flanges oi the rod overlapping the grooves 11 and M, respectively, and the other end of the rod is slipped over the wrist pin 3.' lit is locked and centered in position by the thumb screws i.

These connecting rods as at present made are provided with an opening 20 and through this is poured the Babbitt metal 21. Any joints in the mold may be wrapped or packed with thread or asbestos, and in practice ll find that a light strand oi? asbestos or cotton wick packing at the joints a is all that is required to prevent escape oi the metal.

When the work has been completed the screw 8 will serve to force the rod on? the wrist pin 3,

The simplicity and advantages of? the device will be obvious to those using devices of this general character.

"What it claim is:

l lln a device of the hind described, a connecting rod support comprising a standard having a pin adjacent one end and oldset at the other end, a core block section carried by the ofitset portion of the standard, and a cobperating core bloch section adapted to be sup orted from the first section and detachab e therellrom.

2. In a device of the hind described, a standard, the upper end of the standard being odset, a block carried b and within the oset, a, core integral with t e block and having an annular groove at its base and a centrally proiectin pin, a second block having a core portion oapted to fit over said in and en gage the core of the first mentioned block, and having also an annular groove, and means for locking the core sections together.

3. lln a device of the kind described, a standard having a pin adapted to enga e the wrist-pin opening of a connecting to said standard being ofiset, a combined mold and core section carried by the ofiset portion and adapted to engage the head of the conneoting rod, and a ear, cooperating mold Nil and core section adapted to engage said head and to be locked to the first mentioned mold and core section.

4. In a device of the kind .descrlbed, a standard, a pin carried by the standard adjacent one end, said standard havmg a threaded opening adjacent said pin, a thumb screw working through said openlng from the side opposite the pin, lateral extensions formed on the standard, lugs carried by said extensions at right angles to the. standard, adjusting screws working through said lugs, and mold and core sections supported from the standard at the end opposite said pinix 5. In a device of the kind described, two detachable mold and core sections, each section comprising a block, and a core, the blocks being grooved at the base of the cores, one of said blocks and cores having a central opening, a pin carried by the core of the other block adapted to fit said open- Y ing, and means for supporting the block the core of which carries said pm, said means also supporting a connectmg rod during process of reb bitting.

In testimony whereof I afiix my signature.

ARTHUR M. DENNING.
